On August 4, 2026, the US Federal Aviation Administration (FAA) announced the allocation of a total of 870 million US dollars in funding for the modernization and expansion of airport infrastructure in the United States.
The funds are distributed across 339 individual grants for airports in 44 US states and two US territories. The funded projects include major undertakings such as the construction of a new access road at Los Angeles International Airport, with a budget of $289 million, and roof renovations to the terminal buildings at Miami International Airport, totaling $50 million. The funding comes from the Infrastructure Investment and Jobs Act, passed in 2021, which provides a total of $15 billion over five years for civil aviation infrastructure. Alongside these government grants, preparations are underway for a separate major project at Washington Dulles International Airport, which will involve investments exceeding $20 billion over the next ten years.
Key areas of current funding allocation and major projects
The funding package presented by the FAA aims to adapt both busy international hubs and smaller regional airports in the US to increasing passenger volumes. Los Angeles International Airport (LAX) will receive the largest single allocation in the current tranche. The allocated $289 million will be used to construct a new road connection to the terminals, improving landside access and reducing congestion in the airport's approach area.
At Miami International Airport (MIA), $50 million is being invested in the repair of terminal infrastructure. The primary focus is on the renewal and reconstruction of roofs damaged by weathering. The FAA emphasized in its announcement that the funds are being released quickly to avoid construction delays given the high demand for passenger traffic. However, the announcement, dated August 4, 2026, did not include specific timelines for the start or completion of individual projects.
Consideration of regional airports and technical equipment
In addition to major airports, the federal agency's package includes numerous projects at regional locations. For example, Akron-Canton Airport in Ohio will receive $9,1 million for the renewal of passenger boarding bridges and the renovation of service buildings. Juneau International Airport in Alaska has been awarded $4,2 million, earmarked for the purchase of new snow removal equipment for the runways.
Additional funding will go to Charleston International Airport in South Carolina, which will receive $3,7 million for a terminal building expansion. Sugar Land Regional Airport in Texas has been approved for $3,5 million for a complete runway renovation. The underlying Airport Infrastructure Grants program allows the funds to be used for a wide range of projects, including taxiway upgrades, baggage handling system improvements, road connections, security enhancements, and general site planning.
Legal basis and distribution mechanism
The legal basis for the current funding package is the bipartisan infrastructure bill passed in 2021. This bill provides for a total investment of US$15 billion in the US airport system over a five-year period. The distribution of the regular annual allocations to the respective operating companies is primarily based on the annual passenger numbers at each location.
If an airport's regular allocations are insufficient to cover planned infrastructure projects deemed necessary by the agency, the FAA can approve additional special funding. U.S. Transportation Secretary Sean Duffy and FAA Administrator Bryan Bedford, when presenting the figures, emphasized that the investments are intended to strengthen the operational reliability and efficiency of the air transportation system. The allocation, dated August 4, 2026, follows several previous funding rounds released throughout 2026 for runway rehabilitation and terminal improvements.
Planned major renovation at Washington Dulles International Airport
Regardless of the $870 million package, preparations are underway for a comprehensive modernization program at Washington Dulles International Airport. As announced by the operator, the Metropolitan Washington Airports Authority, United Airlines, and the U.S. Department of Transportation, an investment of more than $20 billion is planned for the airport over the next ten years.
The project entails new construction and renovation work across an area of more than 460.000 square meters. Plans include the complete replacement of the existing temporary terminals C and D with modern terminal buildings, the modernization of the main terminal including the check-in areas, the expansion of security checkpoints, the installation of new baggage sorting systems, and the creation of additional gate capacity and waiting areas. The airport's historic main building, designed by architect Eero Saarinen, will remain untouched during the construction work and will be restored.
As part of the redesign, the underground AeroTrain transport system will be expanded and supplemented by a central pedestrian tunnel. This will allow the airport to gradually replace the mobile shuttle buses, known as Mobile Lounges, which have been in use for decades. Construction is already underway on the new Terminal E, which will include 14 gates for United Airlines and is scheduled for completion by the end of 2026.
